无法转换未定义或空值？

Question

const Discord = require('discord.js');
const randomPuppy = require('random-puppy');
const subreddits = [
"memes",
"DeepFriedMemes",
"bonehurtingjuice",
"surrealmemes",
"dankmemes",
"meirl",
"me_irl",
"funny"
]

exports.exec = (client, message, args, user) => {
    var randSubreddit = subreddits[Math.round(Math.random() * (subreddits.length - 1))];

    randomPuppy(randSubreddit)
        .then(url => {
            const embed = new Discord.RichEmbed()
                .setFooter(`${randSubreddit} ● Subreddit`)
                .setDescription(`[Image URL](${url})`)
                .setImage(url)
                .setColor(0);
            return message.channel.send({ embed });
        })

};

嘿，伙计们，大约一年前留下了不和谐的编码，我又回到了这个错误（标题）一年前它工作得很好，现在什么都没有。 （没有改变任何东西）。 我对现在发生这种情况的方式或原因感到有点困惑。

感谢任何帮助，因为我不知道。

提前谢谢你:)

编辑 - 未运行 Discord.js v12，因此 RichEmbed 仍然适用。 :)

const Discord = require('discord.js');
const randomPuppy = require('random-puppy');
const subreddits = [
    "memes",
    "DeepFriedMemes",
    "bonehurtingjuice",
    "surrealmemes",
    "dankmemes",
    "meirl",
    "me_irl",
    "funny"
]

exports.exec = (client, message, args, user) => {
    var randSubreddit = subreddits[Math.round(Math.random() * (subreddits.length - 1))];
    randomPuppy(randSubreddit)
        .then(url => {
            const embed = new Discord.RichEmbed()
                .setFooter(`${randSubreddit} ● Subreddit`)
                .setDescription(`[Image URL](${url})`)
                .setImage(url)
                .setColor(0);
            message.channel.send({embed});
        })

};

问题出在这条线上。 embed 未定义。

        return message.channel.send({ embed });

如果这在过去有效并且最近才停止工作，那么我怀疑这是两件事之一； 您的数组中的某个子目录不再存在，或者 api 已过时。

您可以通过在 return 语句之前添加 console.log(embed) 然后逐个删除每个 .function() 调用直到嵌入不再 === undefined 来调试它。

可能也值得npm install 再次每个包。
